Lou:
Allan presents the better advice below. Ignore my previous post until you
are sure the battery is bad.

Lou,
There is nothing in your message that definitively tells me that you have
either a bad cell or a bad battery. "Minor corrosion on one terminal" is
normal behavior, especially if the installer didn't coat the terminals at
installation. "One cell was not using as much water as all the rest" is a
matter of perception. You write yourself that "everything looked fine." It
seems to me that you're jumping to conclusions based on the comment of
another Wrench without doing sufficient testing first. Get the client to
put a measured load on the system without charge. This isn't hard to do
with an amp-hour meter in the system - you want a steady load of about 55
A (a C/20 load). If you have a bad cell, it'll show up soon enough.
For now, I'm on Interstate's side.
Hope this helps,
Allan
